OSCILLATING VALVE.

Specification of Letters Patent.

Application filed August 21, 1E 12. Serial No. 716,299.

To all whom, z t may concern Be it known that I, FRANK A. GooDNEss, acitizen ofthe United States, residing at Marion, in the county of Grantand State of Indiana, have invented certain new and useful Improvementsin Oscillating Valves, of which the following is a specification,reference being had to the accompanying drawings.

The present invention relates to new and useful improvements in valvesand more particularly to a rotary oscillating valve which is designed tobe used in conjunction with internal combustion engines.

The primary object of'the present invention is to provide a valve of thecharacter aforesaid which will be positive in operation and during theoscillation thereof, it will automatically clean the valve seat.

A further object of the present invention resides in constructing avalve casing for a valve of the aforesaid character, which may bemounted within the cylinder of the engine to form a more rigidconstruction to resist the internal strains exerted owing to theexplosions.

The invention has for a still further object a simple, durable andeflicient construction of apparatus of this character, the parts ofwhich may be cheaply manufactured and readily assembled and installed,and which will require practically no attention to maintain in properrunning order. And the invention also aims to generally improve thisclass of devices and to render them more useful and commerciallydesirable.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that the right is reserved to any changes, alterations, andmodifications to which recourse may be had within the scope of theinvention and without departing from the spirit or sacrificing theefficiency of the same.

In the said drawings, Figure 1 illustrates the side elevation of acylinder having my invention applied thereto. Fig. 2 is a detail sectiontaken through the cylinder illustrating the valves. Fig. 3 is ahorizontal section taken through one of the valve casings, Fig. 4 is adetail perspective view of one of the valves. Figs.'5 and 6 are detailtransverse sections taken on the lines 5-5 and 6-4) respectively of Fig.4:.

Reference now being had to the acconr panymg drawings whereincorresponding parts are designated by like numerals throughoutthe-several views, the numeral 1 indicates an ordinary cylinder casinghaving the usual reciprocating piston 2 mounted therein. Mounted in theupper end of the cylinder 1 is a pair of parallel extending in take andexhaust valve casings 4 and 3, res'pectively, between which is formed anexplosion chamber 5. Each of these valve casings is preferably mountedwithin the cylinler walls which will obviously provide a more rigidconstruction, said valve casings being preferably of cylindrical form.The intake valve casing is provided with an intake port 6 and formedopposite from the said port 6 is an inlet port 7 leading from the valvecasing 4 to the explosion chamber. The exhaust valve casing 3 isprovided with an exhaust port 8 leading from the explosion chamber 5 andan exhaustport 9 which is in communication with the exhaust manifold ofthe engine. Mounted within these valve casings are rotary oscillatingvalves, each of which is mounted upon the shaft 10 and extendslongitudinally of a casing. This shaft is journaled in bearing blocks 11and 12, which are detachably mounted within opposite ends of the valvecasing. Fixed to each of the shafts 10 are inwardly extending arms 13which have pivotally connected to their free ends the valve actuating.rod 14. These valve rods 1st are operatively mounted within guides 15formed upon the outer periphery of the cylinder casing, and the rodshave also mounted thereon coil springs 16 which normally hold the valvesin a closed position. To operate these valve rods so that the valveswill be opened and closed at the desircdintervals to complete the intakeand discharge of the gases to the cylinder, I provide a pair of cams 17and 18, respectively, upon the periphery of which is adapted to ride thelower extremity of the valve rods 14. These cams 17 and 18 are eachprovided with gear wheels 19 which are in mesh with a gear wheel 20keyed upon the crank shaft of the engine whereby upon the rotation ofthe crank shaft, the cams will also be operated, which in turn willobviously operate the valves.

'spectively. The arms 22 are integrally connected by a longitudinalguide bar 27.- Slidably mounted upon the valve supporting arms 23 is asegmental valve blade 24. The apex of this valve blade 24 is providedwith a longitudinally extending recess 25 for the reception of the arms23 and the 'leaf spring 26, which is rigidly fixed at its medial portionto the sleeve 21. The outer or free ends of the leaf spring 26 arecurved, and rest upon the inner face of the valve blade, therebyproviding means for holding" the blade in an extended position, for apurpose which will be hereinafter described. The outer face of the valveblade 24' is curved to conform to the configuration of the innerperiphery of the valve casing, and the longitudinal edges thereoftapered to a point, as at 28, to form cutting edges, as shown; The outerface of the guide bar 27 is also curved to conform to the configurationof the inner periphery of the valve casing, so that upon the oscillationof the valve within the casing it will be allowed to operate.

It is obvious from the foregoing description, takenin connection withthe accompanying drawings that the guide bars 27 of the valves eachoperate across'the ports 7 and 8 leading from the valve chambers to theexhaust chamber and obviously clean the same to prevent the accumulationof any hydrocarbon or other foreign matter which should happen toaccumulate therein. The valve blades 24 also operate across the ports 6and 9 of thevalve casing and the tapered edges thereof, indicated by thenumeral 28, scrape along the inner periphery of the valve casing therebyalso removing any, hydrocarbon or foreign matter which should happen toaccumulate thereon. It is apparent that the leaf spring 26 normallyholds the valve blades in an extended position, thereby closingcommunication between -the inletand outlet ports and, as these valveblades are slidably mounted upon the arms 23, it is to be noted thatupon the explosion within the cylinder, the internal strains thereofwill be exerted uponthe valve blades which however will effectuallyprevent any escape of the gases through the intake or exhaust ports. f

A valve forinternal combustion engines. comprising a casing, an oscillatory shaftmounted therein, a valve blade movable with said shaft and radiallymovable with respect thereto, and means yieldingly holding said valveblade in frictional en gagement with-the casing wall.
